The Palacio da Pena dominates Lisbon and the Atlantic coast with its eclectic Moorish- and Rococo-influenced architecture. The library, inside the Palacio Nacional de Mafra, contains over 4,000 works. The red façade of the Palace of the Marquis of Fronteira, which survived the earthquake that destroyed Lisbon in 1755, conceals splendid azulejos, tile panels painted in shades of blue.
